The new drive for justice has been fueled by the discovery of a military document called the Libro Amarillo, the 'Yellow Book' - a 254-page book produced by the Intelligence Department of the Estado Mayor Conjunto, El Salvador's military high command during the civil war. It is the first list of human targets assembled by the military high command during the war to ever be publicly revealed.
Since it was discovered in 2010, researchers have been carefully confirming the Yellow Book's authenticity and visiting the families of those in it, so the book is only now being revealed.
Assembled between 1978 and 1987, the book contains photographs of nearly 2,000 civilians that it identifies as "delinquent-terrorists", and details their known or suspected leftist political affiliations.
"The majority were intellectuals, writers, journalists, professionals and union members. Some are also workers and campesinos," says Carlos Santos, a human rights activist who has been researching the book. So far, researchers have determined that about 200 people in the book were murdered and disappeared, many by death squads.
During the war, the Salvadoran military claimed that the death squads were independent groups. But, Santos says, "the Yellow Book is evidence that the Salvadoran state violated human rights systematically in this country".
